BACKGROUND

The field of the invention relates generally to chairs and moreparticularly to chairs having a tray assembly.

Known chairs, which are collapsible, are popular with consumers becausethey can be readily folded and stored. Such features enable chairs to betransported and used during recreational activities, such as duringcamping. Known collapsible chairs include a frame that is selectivelymoveable between a collapsed or folded configuration when the chair isnot in use and a non-folded configuration during use. A fabric framecover is coupled to the frame to define a back portion and a seatportion of the chair such that a user may sit on the seat portion andhave his or her back positioned against the back portion. Suchcollapsible chairs may also include arms or armrests that have a cupholder. The cup holder enables the user to place, for example, adrinking cup within the cup holder.

However, some known collapsible chairs may not include a portion forpositioning, for example, a plate thereon. As such, while a user may beable to place a drink within the cup holder during a meal, the userwould need to position a plate of food on the ground or, more commonly,on his or her lap. Therefore, known collapsible chairs may not provide aconvenient or comfortable setting for the user to eat from a dish (forexample, a paper or plastic disposable plate) of food while sitting inthe chair. Moreover, known collapsible chairs may not provide aconvenient or comfortable setting that includes a tray assembly thatenables a user sitting in the chair to be provided with a surfacesuitable for allowing a user to rest an object (for example a laptop, amobile phone, a book, or notebook) while sitting in the chair.
